11 Claims.

i This invention relates generally to handles and Inore especially to handles for teakettles, coffee pots, pails and other containers having a wire or like bail and upon which is mounted a, hand gripping portion termed a handle.

The present invention is directed to improve- ``nents upon the handles illustr ated, described and claimed in Patent No. 2,319,147 dated May 11, 1943, and copending Patent No. 2,371,639 dated March 20, 1945, reissued as Reissue No. 22,749 dated April 30, 1946'. V Both patent disclosures 'are directed to identical half handles, each having a bail groove, a locking tongue to one side thereof and a looking groove to the opposite side of the ball groove and a like distance therefrom, all grooves extending longitudinally of and coextensive with said handle, the half handles being assembled upon a bail or together by longitudinal end to end presentation of one to the other. The first patent is directed to a handle wherein the tongues and looking grooves are complementary and equal in cross-section throughout their length while the second patent is directed to a handle wherein the tongues and looking grooves are progressively tapered in cross-section for 'self-looking or wedgelooking purposes.

The present invention is applicable to either type of handle and is directed to a discontinuous looking arrangement' thereby permitting of the formation of a, hollow or tubular handle.

One chief feature of the present invention when embodied in molded h-andles is the provision of end cups at opposite ends which provide predetermined formations to be filled with handle forming material and which serve as molds for same in the handle formation. These included cups permit handle molding to be effected by molds that have the desired external handle conformation forming cavity and a smaller convex "molding means that forms the central cavity in the handle and seals off the cups at their confronting inner concave faces. The cups preferably are formed as sheet metal stampings and may be of different metals or other material and formed by casting, molding or the like as well. p Each type handle, regardless of length or external conformation, requires but two end cups which are identical or similar. It will be obvious 'that production of either type handle is extremely The full nature of the invention will be 'understood from the accompanying drawings and the following description and claims:

In the drawings Fig. 1 is a side elevation of a handle embodying the invention applied to an ofifset portion of a bail (see certain dotted lines) or a coffee pot or smoothing iron (shown partly in section), see the full lines, saidhandle herein having a barrel-like conformation; that is of a. greater diameter at the middle than at either end.

Fi 2 is a central sectional view through the handle and handle support and is taken on line 2-2 of Fig. 1 and in the direction of the arrows.

Fig. 3 is a perspective view looking into `one of the hollow half handles shown in Fig. ,2.

Fig. 4 isa perspective *View 'of an end cup in such a'handle. h i

All the aforesaid illustrates the invention as applied to .and incorporated in the second patent handle.

Fig. 5 is a perspective view similar to Fig. 3 and of the inventionas applied to and incorporated in the first patent handle.

Fig. 6 is a transverse sectional view thereof and is similar to Fig. 2. h

Since each of the aforesaid patents describes in detail the application of said handle to a bail or the like by end to end or longitudinal association of one-half handle to another with the bail included therebetween and the handle of the present invention is illustrated in applied position in Fig. 1, further reference thereto will be omitted and attention will be directed to the present half handle invention details and Construction. I V

Each half handle of the second patent type in cludes a body portion having two parallel and copl anar faces l I, a' cylindrical or similarinner concave surface l2 and a, cylindrical, barre] or like shaped convex external surface I 3.

` At each end is a cup I 4 having the end wall !5, defined by a semi-circular outlined flange IE and the fiat flange |1 connects the ends thereo f. Herein the flat fiange has a groove defining, de'- pressed, semi-cylindrical portion Is and spaced therefrom and parallel thereto is the semi-frusto conical groov defining depression 19 andspaced 'a like distance oppositely from groove a is the upwardly projecting seml-frusto-conical projection forming portion 20 complementary to groove or depression s. i y u In the production of the half handle illustrated ;the exterior mold in its cavity will seat at each end the two cups in the relation shown in Fig. 3. 'Then 'a measured amount ofmaterial is supplied In Figs. 5 and 6 numerals of theone,hundred series indicate like or equivalent' part's similar to those in Figs. 1 to 4 inclusive and designated by the corresponding numbers of the primaryseries. of numbers. The result isa hollow half handle having .cup filled reenforced end's. The locking portions herein, however, instead of beingsemig This provides a u) having an outwardly projecting tongue with a reduced neck connection thereto and parallel to but spaced from the central groove, said tongues being longitudinally aligned and each closure having a groove complementary to said tongue and neck and spaced oppositely from the central groove the same distance as the tongue and neck is spaced therefrom and parallel to both, the last mention ed complementary grooves being longitudinally aligned, the. tongues and' grooves spaced from the central grooves each having a tapering form, the said aligned tapering tongues and tapering grooves being substantially identical respectivey.

4. A renforcecl hollow handle structure comprised of? apair of similar half handles, each half handle including a body shell and end closures at' ppositeends'crsaid Shell, each closure having fmusto-conical in character are semi-cylindrical in: character.

Ecept for\ the exposure of the semi-circular band portions !6 and I [6 and the end plates |5 and l 15, theextjernal appearance of the hollow handles hereinare thesame as the handles illustrated the second. and first patents aforesaid respectively. T

' Not only are the strain portions reenforced by thelcups, butitis obvious the'discontinuous type of connection onlyrequires partial lapping of the halfhandles in lon'gitudinal offset relation and then` registration thereof by movement axially ofethe 'handle of but little more than the depth While theinvention has been' illustrated and describedin 'great detail in the drawings and foregoing descriptiomthe same isto be considered as illustrative and not restrictive in character.

The several modifications described herein, as

well as others which Will readily suggest themr u selves to persons skilled in this art, all are considered to be within the broad scope of the invention, reference being .had to the appended claims.
